Are all parallelograms a rectangle?
No, because to have a rectangle, you need to have four right angles, and parallelograms dont have to have right angles. However, all rectangles are parallelograms.
What is true of rectangles that isn't true of parallelograms in general?
All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
How many right angles in a parellelogram?
Generally, there are no right angles in a parallelogram, but rectangles and squares can be seen as special parallelograms, as they have all the qualities needed to be classed as parallelograms, and in addition, they have four right angles.
Are all parallelograms and rectangles the same?
No. Rectangles are parallelograms with all right angles, while parallelograms just have 2 sets of parallel lines.
What parallelogram has no right angles?
All of them, except rectangles. (Rectangles are special parallelograms.)
Are all parallelograms a rectangle?
No, because to have a rectangle, you need to have four right angles, and parallelograms dont have to have right angles. However, all rectangles are parallelograms.
All rectangles are parallelograms. are all parallelograms rectangles explain.?
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
What is all parallelograms with four right angles?
Squares

No. Rectangles are parallelograms with all right angles, while parallelograms just have 2 sets of parallel lines.
What is the counterexample for all parallelograms are rectangles?
any parallelogram that does not have right angles.
Opposite angles of all parallelograms are always?
opposite angles of all parallelograms are always equal.
Is it true some rectangles are not parallelograms?
No. All rectangles are parallelograms, specifically those with two pair of parallel sides and all right angles.
What parallelogram has no right angles?
All of them, except rectangles. (Rectangles are special parallelograms.)
Are rectangles are parallelograms?
Parallelograms do not have right angles. A rectangle is a parallelogram but a parallelogram is not a rectangle.
Why are parallelograms not rectangles?
Parallelograms do not have right angles. A rectangle is a parallelogram but a parallelogram is not a rectangle.
